There is no hard and fast rule of mileage or months. You’ll know when to replace running shoes if you examine them once a month for wear in the following areas:
- Uppers – Look for any separation along the sole, and the vertical part at the back of the heel must be perpendicular to the floor or the shoe could be throwing off your alignment. Check the inside of the heel counter for wear as well.
- Midsole – The layer between uppers and tread should not have creases, wrinkles, or discoloration indicating breakdown of material. It also should not flex too easily at the toes or twist along the sole.
- Outsole – Check for wear in the tread or weak, soft spots that could indicate breakdown of the soles.
If you see these signs of wear, replace the shoes. It’s not worth damaging your feet to keep using them. Please don’t donate worn out shoes and pass your problems on to others, but check if they can be recycled.
